lib.rs:

Format-preserving encryption algorithms.

Example

extern crate aes;
extern crate fpe;

use aes::Aes256;
use fpe::ff1::{BinaryNumeralString, FF1};

let key = [0; 32];
let radix = 2;
let pt = [0xab, 0xcd, 0xef];

let ff = FF1::<Aes256>::new(&key, radix).unwrap();
let ct = ff.encrypt(&[], &BinaryNumeralString::from_bytes_le(&pt)).unwrap();
assert_eq!(ct.to_bytes_le(), [0x75, 0xfb, 0x62]);

let p2 = ff.decrypt(&[], &ct).unwrap();
assert_eq!(p2.to_bytes_le(), pt);
